Rsync calls exit_cleanup() upon reception of SIGUSER1. The only
exception to this is if it is already inside the exit_cleanup()
function. It only sends this signal when a code path causes an
abnormal exit condition, and then the signal is only sent to any
process IDs that it spawned (as recorded by do_fork()).
The generator also uses SIGUSER2 to signal the receiver at the end
of the run that it is time to exit (so that both processes exit at
the same time).

I'm not sure what you mean by this. Is this signal being sent to
rsync via some other means?
